A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, porcelain (tooth colored crown) are the most popular. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Reasons for crowns:
Broken or fractured teeth.
Tooth has a root canal.
Bridgesconsists to two crowns that go over two anchoring teeth (abutment teeth) and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.
Dental bridges are highly durable and will last many years, however they may need replacement or need to be re-cemented due to normal wear.
Reasons for a fixed bridge:
Fill space of missing teeth.
Maintain facial shape.
Prevent remaining teeth from drifting out of position.
